| 0.0 | 0+ | ≈ 0.8 ms % α ≈ 50 % SF ≈ 50 | From observation of fission activities of granddaughter 256Rf, the authors of 1984Og03 and 1986Mu10 had concluded that predominant decay mode of 264Hs g.s. is α decay. From recent observation of short-lived spontaneous fission activities, 1998HoZV deduced that α and SF branchings are 50%, if both activities are from the 264Hs g.s., although an isomeric state could not be ruled out (1998HoZV).
